I've run across them before, but I haven't ever ordered anything from them. I see from the "about us" section of their website that they're not a nursery, but rather a sort of broker for the sale of native plants from other nurseries.

They basically broker sales of native plants from a number of growers in the eastern US. Plants they offer are channeled from grower nearest your location. Never dealt with them, but they can hook you up with species that are not readily found.

Earth is a galactic insane asylum where the inmates have been left in charge.
